能抓下五月柱上所有的彩带吗？
吉姆：五月柱顶上垂下的长彩带，有甚么用？
Jim: What are those long ribbons hanging down from the top of the Maypole for?
曲线应该是三维的，其高点在中心，向各个方向辐射，有些象从五月柱上散出的彩带。
The curve should be three-dimensional one, with the high point in the center and curved lines radiating in all direction, somewhat as streamers from a maypole.
